There are still a lot of Lascivia's minions who stayed behind. I think our best chance is to find a guard who knows a lot about Killek, and willing to show us where he is. They're Elite, so you'll have to best them in combat before they'll respect you enough to speak to you.

One of the most interesting things about this dragon lair is the variety we're seeing among the Draconians living in it! I'd like to study the different types to find out what's causing the mutations. Bring me blood samples from every Draconian you can ﬁnd so I can compare them.

A new creature has been spotted deep within the reaches of Vasalkar's Lair. I believe that Nulgath the ArchFiend has corrupted some of the draconic creatures who dwell here. Find and subdue any you come across so I may determine the extent of the corruption.
